Chest pain is a very common reason people seek medical care. Pain may be sharp or dull, although some people with a chest disorder describe their sensation as discomfort, tightness, pressure, gas, burning, or aching. Sometimes people also have pain in the back, neck, jaw, upper part of the abdomen, or arm. Other symptoms, such as nausea, cough, or difficulty breathing, may be present depending on the cause of the chest pain.
Many people are well aware that chest pain is a warning of potential life-threatening disorders and seek evaluation for minimal symptoms. Other people, including many with serious disease, minimize or ignore its warnings.
Sababu za Maumivu ya Kifua
Many disorders cause chest pain or discomfort. Not all of these disorders involve the heart. Chest pain may also be caused by disorders of the digestive system, lungs, muscles, nerves, or bones.
Sababu za kawaida
Overall, the most common causes of chest pain are
Disorders of the ribs, rib cartilage, chest muscles (musculoskeletal chest wall pain), or nerves in the chest
Inflammation of the membrane that covers the lungs (pleuritis)
Inflammation of the membrane that covers the heart (pericarditis)
Digestive disorders (such as esophageal reflux or esophageal spasm, ulcer disease, or gallstones)
Heart attack or angina (acute coronary syndromes and stable angina)
Undiagnosed causes that go away on their own
Acute coronary syndromes (heart attack or unstable angina) involve a sudden blockage of an artery in the heart (coronary artery) that cuts off the blood supply to an area of the heart muscle. If some of the heart muscle dies because it does not get enough blood, that effect is termed a heart attack (myocardial infarction). In stable angina, long-term narrowing of a coronary artery (for example by atherosclerosis) limits blood flow through that artery. This limited blood flow causes chest pain when people exert themselves.

Some causes of chest pain are immediately life threatening but, except for heart attack or unstable angina, are less common:
Heart attack or unstable angina
A tear in the wall of the aorta (thoracic aortic dissection)
A type of collapsed lung in which pressure builds up enough to obstruct blood flow returning to the heart (tension pneumothorax)
Blockage of an artery to the lungs by a blood clot (pulmonary embolism)
Other causes range from serious, potential threats to disorders that are simply uncomfortable.

Wakati wa kuona daktari
Although not all causes of chest pain are serious, because some causes are life threatening, the following people should seek care in an emergency department right away:
Those with new chest pain
Those who have a warning sign
Those who suspect that a heart attack is occurring (for example, because symptoms resemble a previous heart attack)
These people should call emergency services (911) or be taken to an emergency department as quickly as possible. People should not try to drive themselves to the hospital.
Chest pain that lasts for seconds (less than 30 seconds) is rarely caused by a heart disorder. People with very brief chest pain need to see a doctor, but emergency services are usually not needed.
People who have had chest pain for a longer time (a week or more) should see a doctor as soon as possible, but they should go to the hospital right away if they develop warning signs or the pain has steadily been getting worse or coming more often.
Anachofanya daktari
Doctors first ask questions about the person's symptoms and medical history and then do a physical examination. What they find during the history and physical examination often suggests a cause of the chest pain and the tests that may need to be done.
However, symptoms due to dangerous and not dangerous chest disorders overlap and vary greatly. For example, although a typical heart attack can cause dull, aching, squeezing, or crushing chest pain, some people with a heart attack have only mild chest discomfort or indigestion or arm or shoulder pain (referred pain—see figure What Is Referred Pain). On the other hand, people with indigestion may simply have an upset stomach, and those with shoulder pain may have only sore muscles. Similarly, although the chest is tender when touched in people with musculoskeletal chest wall pain, the chest can also be tender in people who are having a heart attack. Thus, doctors usually do tests on people with chest pain.

Kupima
For adults with sudden chest pain, tests are done to rule out dangerous causes. For most people, initial tests include
Measurement of oxygen levels with a sensor placed on a finger (pulse oximetry)
Electrocardiography (ECG)
Chest x-ray study
Ultrasound study of the heart (echocardiography) sometimes
If symptoms suggest an acute coronary syndrome (heart attack or unstable angina) or if no other cause is clear (particularly in people who are at high risk), doctors usually measure levels of substances that indicate heart damage (cardiac biomarkers) in the blood (at least 2 separate times over a few hours) and do repeated ECGs.
If these tests do not show an acute coronary syndrome, doctors often then do a stress test or CT angiography before people go home or within a few days. However, if a cardiac biomarker measurement, called high sensitivity troponin, is used and that test does not show evidence of heart damage, further testing may not be required. For a stress test, ECG or an imaging test (such as echocardiography) is done during exercise (often on a treadmill) or after a medication (such as dipyridamole) is given to make the heart beat fast or increase blood flow through the coronary arteries.
If pulmonary embolism is suspected, CT angiography (CT with intravenous contrast) of the lungs or a lung scan is done. If pulmonary embolism is considered only somewhat possible, a blood test to detect clots (D-dimer test) is often done. If this test is negative, pulmonary embolism is unlikely, but if the test is positive, other tests, such as ultrasound studies of the legs or CT angiography, are often done.
In people who have had chest pain for a long time, immediate threats to life are unlikely. Most doctors initially do only a chest x-ray study and ECG and then do other tests based on the person's symptoms and examination findings.
Sometimes the cause of chest pain, even after a complete evaluation, cannot be determined.
Matibabu ya Maumivu ya Kifua
Specific identified disorders are treated. If the cause is not clearly benign, people are usually admitted to the hospital or an observation unit for heart monitoring and more extensive evaluation. Pain is treated with acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDS), or opioids as needed until a diagnosis is made.
Mambo Muhimu
Chest pain may be caused by serious life-threatening disorders, so people with new chest pain (within a few days) should get immediate medical attention.
The symptoms of life-threatening and non–life-threatening disorders overlap, so testing is usually needed to determine a cause.
